I am on fastmail and use android without Google Play Services (and would think that a significant proportion of your customers have moved to you from gmail because they care about things that might lead them to avoid google play services). Having said that, I'm happy enough using an IMAP mail client. I would have been much more excited to have good calendar and contacts synchronization with my phone. Please don't make those dependent on google services too.
